Marcello Barnaba commented on COUCHDB-1098:
-------------------------------------------
Yeah - sorry I misunderstood the report from my colleague - tests on couchone
were really unlikely to fail due to the much higher latency between the client
and the server.
So, this is definitely a race condition when the database is stressed very
rapidly. It could sound like a corner case, but it could happen on a busy
application as well. Not WRT the DELETE/PUT sequence, but WRT the POST/GET one
- think about an HTTP server exposing a REST API, and that's exactly what we're
doing on our app. :-)

> Key: COUCHDB-1098
> URL: https://issues.apache.org/jira/browse/COUCHDB-1098
> Project: CouchDB
> Issue Type: Bug
> Components: Database Core
> Affects Versions: 1.0.2
> Environment: Server: CouchDB v1.0.2 on Erlang R14B on MacOS X 10.6.6
> - via the CouchDBX.app bundle v1.0.2.0
> Client: Ruby (CouchRest)
> Reporter: Marcello Barnaba
> Priority: Critical
>
> Hello,
> in our test cases we repeatedly delete, recreate, populate and query the test
> database views to assert the correctness of the data returned. For each test
> group.
> We've experiencing two, *random*, different crashes of the erlang processes,
> one during indexing (I think) of the test data, and another one caused by a
> race condition when deleting and recreating the database - when the test
> group ends. On this gist https://gist.github.com/ffc6960a2b7022826388 there's
> the relevant part of the couchdb access log file, from the beginning to the
> end of the test group.
> Please let us know any other information that you need in order to help
> pinpointing the issue.
> As a side note, it happens on another 1.0.2 installation on Linux/i386 and on
> couchone.com servers - so it doesn't look like platform specific :-).
> Thank you in advance for your support.
> ~Marcello
